Description of particle monitoring module principle
Compared with traditional screening and settling methods, the method of measuring dust concentration by light scattering principle has many advantages, such as wide applicability, fast measurement speed, high accuracy and on-line real-time measurement.
The particulate matter in situ measurement module adopts high-sensitive light scattering photometer (turbidimeter) technology to measure the particulate matter concentration.The particulate matter is cutting through a particle cutter firstly to cut PM2.5 or PM10 particles that we need to measure. After cutting, the particulate matter goes through the injection port and enters the optical measurement room. The source generates 880nm of infrared light to scatter on the particles, and the detector located at a 90° Angle captures the scattered light. Through the relationship between the scattered light intensity and the calibrated particle mass concentration, the mass concentration is calculated and transmitted to the data acquisition and processing subsystem in real time.
